Title: Foreign matter adhesion preventive method and foreign matter adhesion preventive device
Inventor: TSUBOI KIYOSHI
IPC: C02F5/00
Filed: 2000-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a foreign matter adhesion preventive method and foreign matter adhesion preventive device constituted to prevent the adhesion of foreign matter in fluid on a wall surface, etc., by largely growing the foreign matter. SOLUTION: The foreign matter adhesion preventive method consists in applying an electric field to the liquid in which the foreign matter, such as ionized material, is dissolved to activate the foreign matter and to increase chances that respective pieces of the foreign matter come into contact with each other, thereby bonding respective pieces of the foreign matter and largely growing the foreign matter. As a result, the adhesion and deposition of the foreign matter to the inner wall etc., of piping are prevented. The electric field is preferably applied to the liquid in the direction nearly orthogonal with the flow of the liquid. The foreign matter adhesion preventive device has an electric field impressing means 2 for activating the foreign matter by applying the electric field thereto.  The electric field impressing means 2 comprises an annular body 3, an iron core 4, a coil 5 and a power source 6. A pair of electrodes may be used as the electric field impressing means 2. The electrodes are formed by curving, are made smaller in surface areas or formed to a needle form or may be provided with a plurality of needles by regulating the density of the needles. Further, the fluid piping 8 is formed of a ferroelectric substance in some cases.
